CHANNE LING-MACHINE.

Patented. Jan; 14, 1908.

Application filed August 31- 1906- Serial No. 332.836-

-HAIGHT, of Sherbrooke, Province of Quebec,

Canada, have invented certain new and useful Im rovements in Channeling-Machines; and I o hereby declare that the following is a full, clear, and exact description of the same.

The invention maybe said to consist of the several combinations and arrangements of parts hereinafter described, and illustrated in the accompanying drawing to which reference must be had for full comprehension of the invention and wherein similar reference characters indicate the same parts.

The main features of this invention are: first; the combination of aradial tool for channeling or other urpose, and a portable carriage:- second; t e carriage for the tool a being mounted upon wheels and provided devices for rigidly supporting the body thereof independently of the wheels which from beneath the plane in which the tool es while working: third; the location of the tool below the horizontal member of the truck frame and between the said devices for rigidly supporting the machine independently of the wheels:

fourth; the machine being adapted to be swiveled or swun about a vertical axis preferably in vertica linewith one of the said supporting devices: fifth; particular specific means for holding the wheels relatively to the truck frame either in supporting position-or lifted, and additional means for locking the tool carrying member proper at right angles to the truck.

In the accompanying drawings, Figure 1 is an end elevation of a channeling'machine embodying the improvement; I Fig. 2 is a longitudinal vertical sectional view thereof taken on line AA of Fig. 1; Fig. 3 is an enlarged horizontal sectional view taken on line BB of'Fig. 1 and illustrating particularly the means for detachably locking the wheel support to the truck frame in different adjustments. Fig. 4 is a transverse sec.- tional viewon line CC of Fig. 1 and illustrating the same details'as Fig. 3; Fig. 5 is a erspective view of the machine and the c anneling tools for use'therewith; and.

Fig. 6 is a transverse vertical sectional view taken on line DD Fig. 2 and illustrating particularly the sliding connection between the longitudinally adjustable tool carrier and the member in which it is slidably mounted.

. pedestal The truck comprises a pair of channel irons b, b, disposed with their backs towards each other and a sufficient distance apart to accommodate between them the lower truncated conical end 0 of a pedestal d to be presently further alluded to, the said lower end being secured to the channel irons b, b, by bolts f. The said channel irons are bolted at their ends to a pair of boxes 9 having downwardly projecting internally screw-threaded sleeves 'h. These sleeves form portions of the before mentioned-deri idl su ortin the carria e inde enderl tly hf th ze wheeli, the third 0% the said devices bein clamped in the upper end of the g above mentioned. A pair of jack screws 4, are screwed downwardly through the boxes g and sleeves hand their lower ends 'arediminished and have secured rigidly thereon, balls Z which are adapted to fit into sockets formed in a pair of feet m having their treads provided with teeth n and the upper annular edge of each formed with lugs 0 adapted to be bent inwardly and retain the balls against entire displacement while allowing them the freedom necessary in a ball and socket joint. In order -to aflord means for clamping to the .-pedestal d the third device for rigidly holding the machine while it is operating, the upper end of the said pedestal is cut away to present a:semicircular part 2 having perforated lugs 1' and s at opposlte ends and a clamping cap also of semicircular form pro- 'vices (which may be termed jacks) for vided and has lugs t coacting with the lugs r to form a hinge and lugs a adapted to coact with the lugs s. The hinge In S t and 1' are connected by an ordinary pint e 7) while the lugs s have a bolt .10 pivotally connected thereto and adapted to project between the lugs u and have a clamping nut :cscrewed thereon. v A column 2, in the form of a pipe, has its lower end clamped in the clamping device, just described, and its upper en internallyv screw-threaded with a jack screw 3 screwed therein and a serrated foot 4 is connected to the upper end of this jack screw by a ball and socket connection as shown in Fig. 2.

As thus far described, the truck frame and means for supportin' the same rigidly at different working leve s are disclosed, and for the purpose of moving this mechanism to different working POSitlOIlS' a pair of bearingbrackets 7 are bolted to the rear side of the main transverse truck member I) and has a crank shaft 8 bearing therein and having a pair of crank arms 9 Secured rigidly upon its opposite ends and carrying a pair of traction wheels '10-. The shaft is loose in its bearings to enable the wheels to be swung either to position supporting the truck frame or above the same, and these wheels are locked in either position by a pair of latches each consisting of abolt 12 located slidably in the shaft bearing and pivoted to a cam lever13, while an expansile helical spring 14 yieldingly retains the bolt in position to engage either of a pair of holes 15 in-the crank arm adjacent thereto.

, The tool carrying memberis located beneath'the truck frame and comprises a guiding part 20 of female dovetail cross section, carrying a truncated conoidal standard 20* corresponding in dimensions to the interior of the lower end 0 of the pedestal (1 into which it fits rotatably. The top of this standard 20* is perforated and a washer 26*- rests thereon and is of sufficient diameter to overlap a bearing face 25 presented by an enlargement of the'portion of the pedestal d intermediate the said lower conoidal end and the clamping top. This enlargement also accommodates the head 26 of a center bolt 27 which is passed downwardly through the washer 26* and perforated top of'the standard 20* and is threaded into a hub 28 formed integral with the lower'end of the said standard, thus pivotally connecting the above mentioned guiding part 20 to the truck or carriage. The cylinder 30 in which the tool piston 31 reciprocates, is supported in the guide 20 by means of a ma e dovetail 30* formed u on or cast in one with the top of the cylin er and mounted slidably in the female dovetail 20** of the guide 20.

A screw 32 for feeding the tool is mount ed rotatably in a cross head 33 carried rig-v idly by the guiding member and threaded" through a nut 34 constituted by a threaded boring through the male dovetail, a am nut 35 being located adjacent to the forward end of'the said nut 34, and an'operating handle 36 is rigidly clamped (by a bolt 37) upon the rear end of the screw.

A tiller 40 is secured rigidly upon the top w of the rear end of the guiding member 20, and a pin 41 adapted to be inserted through registering holes in the flange 42* upon the lower conical end 0 of thepedestal dand the flanged lower end 42 of the standard 20*. This pin 41 is for the purpose of locking the ,tool bearing member against horizontal oscillation in the truck, and the tiller affords means for directing the truck in its movement.

, I do not describe the valve for controlling the operation of the tool as it forms the sub ject matter of an application filed by me November 22nd, 1906 under No. 344,552, while (and beneath the truck and the rotary bar and the tool and the mechanism intermediate such parts, are the same as heretofore used in mining, quarrying and the like.

When being moved from one place to another, the truck frame is supported on the wheels, the lower jacks are shortened, or screwed up, and the upper jack is unclamped and removed, if more convenient, the tool can be removed. being arrived at, the lower jacks are extended until the wheels are lifted clear of the ground, the wheel latches are then moved to disengage the locking pins from the crank arms, and the latter, with the wheels carried thereby are swung up to the position shown in Fig. 2. These supporting jacks are then operated upon until the tool is brought to the required level after which the upper jack is caused to bear tightly against the ceiling, cross timbers, or other available abutment surface above the machine. then removed and the machine is ready for operation. 1
